Можешь сократить дроби из упражнений?

Конечно, сейчас помогу сократить дроби! 1) $\frac{-(x+y)}{(x+y)} = -1$ 2) $\frac{-2(a+b)}{(a+b)} = -2$ 3) $\frac{(x+3)}{-5(x+3)} = -\frac{1}{5}$ 4) $\frac{2(b+1)}{-(b+1)} = -2$ 5) $\frac{-(x-3)}{12(x-3)} = -\frac{1}{12}$ 6) $\frac{(a+5)(a+5)}{(5+a)(5-a)} = \frac{a+5}{5-a}$ 7) $\frac{13+x}{(x+13) \cdot b} = \frac{1}{b}$ 8) $\frac{-(y-1)}{-(-1+y)} = \frac{-(y-1)}{(1-y)} = \frac{-(y-1)}{-(y-1)} = 1$ 9) $\frac{2(a-b)}{3(b-a)} = \frac{2(a-b)}{-3(a-b)} = -\frac{2}{3}$ 10) $\frac{5(x-y)}{a(y-x)} = \frac{5(x-y)}{-a(x-y)} = -\frac{5}{a}$ 11) $\frac{x(y+3)}{2(-y-3)} = \frac{x(y+3)}{-2(y+3)} = -\frac{x}{2}$ 12) $\frac{5(-2+a)}{3(a-2)} = \frac{5(a-2)}{3(a-2)} = \frac{5}{3}$ 13) $\frac{(y-1)}{3(-1+y)} = \frac{(y-1)}{3(y-1)} = \frac{1}{3}$ 14) $\frac{a(a-1)}{-(1-a)} = \frac{a(a-1)}{(a-1)} = a$ 15) $\frac{(y-1)(y-1)}{(1-y)(1+y)} = \frac{(y-1)(y-1)}{-(y-1)(1+y)} = -\frac{y-1}{1+y}$ 16) $\frac{(y+1)(y-1)}{(-y-1)} = \frac{(y+1)(y-1)}{-(y+1)} = -(y-1)$ 17) $\frac{-2(a-b)}{(a-b)^2} = \frac{-2}{a-b}$ 18) $\frac{(x-3)}{(3-x)^2} = \frac{(x-3)}{(-1(x-3))^2} = \frac{(x-3)}{(x-3)^2} = \frac{1}{x-3}$ 19) $\frac{(b-1)^2}{(1-b)(1+b)} = \frac{(b-1)^2}{-(b-1)(1+b)} = -\frac{b-1}{1+b}$ 20) $\frac{(a+3)(a-3)}{(3-a)^2} = \frac{(a+3)(a-3)}{(-1(a-3))^2} = \frac{(a+3)(a-3)}{(a-3)^2} = \frac{a+3}{a-3}$ 21) $\frac{(y-2)(y+2)}{(2+y)^2} = \frac{(y-2)(y+2)}{(y+2)^2} = \frac{y-2}{y+2}$ 22) $\frac{-(a-2)}{(2-a)(a+2)} = \frac{a-2}{(a-2)(a+2)} = \frac{1}{a+2}$ 23) $\frac{(x-1)(x+1)}{(1-x)(-x-1)} = \frac{(x-1)(x+1)}{-(x-1)(-(x+1))} = 1$ 24) $\frac{-(x-1)(1-x)}{(x-1)^2} = \frac{(x-1)(x-1)}{(x-1)^2} = 1$
